I have a DH55HC Desktop Board and I cannot get the 825578DC Gigabit Network Connection to connect to my LAN at anything higher than 100Mbps. I have checked all the cables and ports on my switch and had another PC connect to the switch at 1Gbps. I have the latest driver for the Ethernet Controller installed (11.16.87.0) and the latest version of Intel PROSet installed (18.0.1).
Has anyone else had this problem, and if so, what did you do to resolve it?
